About These Birds
Black-crested Tit-tyrant
The Black-crested Tit-tyrant is a small, long-tailed tyrant flycatcher of Andean scrub and paramo in Peru, with a striking upswept black crest and boldly streaked black-and-white plumage. It inhabits dense montane scrub, polylepis woodland, and high Andean shrublands, typically at elevations between 2,800 and 4,200 meters. It feeds on small insects and spiders, foraging actively in dense low vegetation.
Alder Flycatcher
The Alder Flycatcher is a small North American flycatcher weighing about 13 g with a wingspan near 14 cm. It breeds in alder thickets and wet scrub across Canada and the northern United States, identified primarily by its distinctive fee-BEE-o song rather than its plain olive-grey plumage.
